What To Expect During Your HVAC Installation

Did you know that in Texas, anyone who carries out HVAC (heating, ventilation, and air conditioning) work need to have a license? Otherwise, they can’t legally install, repair, or perform anything on someone’s else’s property.

Were you also aware that HVAC contractors should first take out an MC106.1 Mechanical Permit before doing any work? This permit protects you and your home from fire or structural failure hazards that an HVAC unit can cause.

The point here is, HVAC installation requires knowledgeable, experienced technicians. This is the first thing you need to know whether the project is for a new installation or a replacement.

Remember, you’ll spend quite a lot of money on a new HVAC system. So, it pays to know what you should expect to happen during its installation. This way, you can make certain you’ll get your money’s worth.

Here’s what you should know about the process.

Just Before the HVAC Installation

Experienced HVAC contractors consider many pre-installation factors to ensure proper unit set-up. After all, things like the cooling/heating area, equipment size, vents, and ducts, all affect HVAC performance.

This said, you can’t also expect them to finish the job within just a few hours. They’d need time to conduct the following first:

Load Calculation

To ensure proper HVAC installation, contractors follow Manual J.

This is the Residential Load Calculations Standard the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) published.

Besides the above-mentioned variables, HVAC contractors also need to factor in insulation. They should also consider number and placement of windows and doors.

Checking Existing Vents

This is especially true for gas furnaces or boilers. These space heaters need combustion air for them to burn fuel and provide you with heated air. But they also produce potentially-hazardous gases that can build up inside your home.

The contractor should first ensure your home has the necessary vents before installing such equipment.


No matter how high the energy-efficiency rating of an HVAC system is, leaky ducts defeat this purpose. The same goes true for an incorrect-sized unit.

As such, a reliable contractor first ensures you have a fully-functional and problem-free ductwork.

During the Installation Itself

Once the contractors have performed the above, they can now proceed to the exciting part: The HVAC installation itself.

It’s important to give them space and enough time so they can do their job quickly and efficiently. At the same time, you also want to make sure they go through these critical steps:

Confirm Refrigerant Charge

If you’re having an air conditioner installed, ensure the techs check the equipment’s refrigerant charge. This compound is what cools and dehumidifies the air the AC circulates in a building. Too low, and inefficient cooling will occur.

Ensure Thermostat Works

The thermostat is the control center of your heating and cooling system. So, it should work without problems once the technicians have finished the HVAC installation.

To confirm this, the contractors should test it for its powering mechanism, air control, and adjust it accordingly.
